Changing the Tool
The dust protection cap 3 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care
that the dust protection cap 3 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales serv-
ice.
Inserting SDS-plus Drilling Tools (see figure E)
The SDS-plus drill chuck allows for simple and
convenient changing of drilling tools without the
use of additional tools.
– Clean and lightly grease the shank end of the
tool.
– Insert the tool in a twisting manner into the
tool holder until it latches itself.
– Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus
drilling tool can move freely. This causes a cer-
tain radial run-out at no-load, which has no ef-
fect on the accuracy of the drill hole, as the drill
bit centres itself upon drilling.
Removing SDS-plus Drilling Tools
(see figure F)
– Push back the locking sleeve 4 and remove
the tool.
Inserting Drilling Tools without SDS-plus
Note: Do not use tools without SDS-plus for
hammer drilling! Tools without SDS-plus and
their drill chucks are damaged by hammer drill-
ing.
– Insert a key type drill chuck 18 (see "Chang-
ing the Key Type Drill Chuck", page 23).
– Open the key type drill chuck 18 by turning
until the tool can be inserted. Insert the tool.
– Insert the chuck key into the corresponding
holes of the key type drill chuck 18 and clamp
the tool uniformly.
– Set the selector switch 8 to the "Drilling"
symbol.

Removing Drilling Tools without SDS-plus
– Turn the sleeve of the key type drill chuck 18
with the drill chuck key in anticlockwise di-
rection until the drilling tool can be removed.
Dust Extraction with the Dust Extrac-
tion Attachment (Accessory)
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Mounting the Dust Extraction Attachment
(see figure G)
For dust extraction, the dust extraction attach-
ment (accessory) is required. When drilling, the
dust extraction attachment retracts so that the
attachment head is always close to the surface
at the drill hole.
– Press the button for depth stop adjustment 9
and remove the depth stop 1. Press button 9
again and insert the dust extraction attach-
ment into the auxiliary handle 16 from the
front.
– Connect an extraction hose (diameter
19 mm, accessory) to the extraction sleeve
20 of the dust extraction attachment.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
